At first, I though it was meant as a television ident, but with a gaming theme. But I realise this does include logos from gaming companies.
The Only TV Ident I did find relevant to gaming was from this channel.
Fox Kids (2001) – the fast-paced CGI graphics used in this really made the ident look like a platform game, but viewed as a first person shooter. Its variety of colour, imagery, and effects really grabbed the attention for kids, and gamers if it was used for a gaming channel. While it has a lot of lighting and texturing effects in the animation, there isn’t any font or typefacing on this ident.
Sega (1992) – Normally you don’t see a trademark character appear on the logo intro, but this is probably a well-known character ident in game history. Sonic the Hedgehog matches well with Sega’s blue logo, and speeding from one side to another give a really good effect for the logo to fade in, like it came from the dust. The jingle is the same tune that the audience can instantly remember, and they would also tell it’s a game made by Sega by the appearance of Sonic, even if it’s not a Sonic the Hedgehog game.
Nintendo GameCube (2002) – The 3D animation in this is quite clever, as the smaller cub walks around the screen, making a path along the way, the form of a bigger cube. The path forms into a letter, which stands for the word “GameCube”. The purple logo and typeface font is cleverly designed, which would clearly give its target audience the comfort that they are playing from an official console.
